IMPORTANT NOTICE 

IT. S. standards of (lualitv and condition 
for Hard Red Winter Wheat, Soft Red Win- 
ter Wheat, Common White Wheat and White 
Club Wheat, effective July 1, 1917. 

For all other wheat, August 1, 1917. 

The following suggestions made by the 
U. S. Department of Agriculture are good 
ones, and if followed closely should result 
to your benefit. They apply equally to wheat 
as well as corn. 

Interstate and export shipments by grade 
of shelled corn come under the provisions of 
the United States Grain Standards Act. 

GET HIGH GRADES FOR YOUR CORN 

Avoid Expensive Delays by Handling and 
Loading Your Grain Properly 

Licensed inspectors can not with safety 
issue certificates of grade on interstate or 
foreign shipments of shelled corn unless the 
conditions permit them to determine the true 
grade of the grain. If the car is loaded too 
full, or if the grain in it is not uniform as to 
color, moisture content, damaged, foreign 
material, etc., it will be difficult for the in- 
spectors to secure representative samples; the 
car may even have to be partially unloaded 
before the inspection can be completed. This 
may take several days. 



How You Can Aid Inspectors and Facilitate 
Grading 

1. Carefully classify grain received. This 
should be done by quality, condition, and 
color. 

2. Eeserve at least 1 bin for loading pur- 
poses. This is in order that corn can be 
"run," cleaned, conditioned, and mixed. 

3. Clean the grain before loading. This 
helps to insure a high commercial grade and 
tends to prevent deterioration in transit. 

4. Clean the car thoroughly before load- 
ing. Such matter as coal, fertilizer, etc., on 
the floor of a loaded car often results in 
otlierwise good grain being graded as "sam- 
ple" or other low grade. 

5. Carefully cooper cars and watch for 
leaky roofs. 

6. Don't mix in other colors when ship- 
ping grain of a given color. 

7. Leave at least 30 inches of space be- 
tween grain and roof of car. Load the grain 
uniformly and then level it down. Tf the 
proper space is not left between the top line 
of the grain and the roof of the car a repre- 
sentative sample of the grain can not be se- 
cured. 

8. Avoid concentrating dirt, broken grains 
and meal. If such materials accumulate 
near the doors or otherwise, distribute it by 
hand shoveling. 

9. Take a representative sample of the 
loaded grain. This should be done by prob- 
ing in at least five different places with a 
60-inch trier. The sample should be tested 
for every factor to determine what grade the 
grain inspector may be expected to place 
upon the lot.

OFFICIAL GRAIN STANDARDS OF THE 
UNITED STATES FOR WHEAT 

Section 1. Basis of determination. — Each 
determination, other than that of dockage, 
for the purposes of these standards shall be 



made upon the basis of the grain when free 
Jrom dockage. 

Sec. 2. Percentages. — Percentages, except 
in the case of moisture, shall be percentages 
ascertained by weight. 

Sec. 3. Dockage. — Dockage includes sand, 
dirt, weed seeds, weed stems, chaff, straw, 
grain other than wheat, and any other for- 
eign material which can be removed readily 
from the wheat by the use of appropriate 
sieves, cleaning devices, or other practical 
means suited to separate the foreign mate- 
rial present; also undeveloped, shriveled, and 
small pieces of wheat kernels necessarily re- 
moved in properly separating the foreign 
material. The quantity of dockage shall be 
calculated in terms of percentage based on 
the total weight of the grain, including the 
dockage. The percentage of dockage so cal- 
culated shall be stated in terms of whole per 
centum and half per centum. A fraction 
of a per centum when equal to, or greater 
than, a half shall be treated as a half, and 
when less than a half shall be disregarded. 
The percentage of dockage so determined and 
stated shall be added to the grade designa- 
tion. 

(For size and specifications regarding 
sieves to determine dockage of wheat, see 
jmge 21.) 

Sec. 4. .Wheat. — Any grain which, when 
free from dockage, contains more than six 
per centum of grain of a kind or kinds other 
than wheat shall not be classed as wheat. 

Sec. 9. — Test Weight per Bushel. — Test 
weight per bushel shall be the weight per 
Winchester bushel as determined by the 
testing apparatus and the method of use 
thereof described in Bulletin 472, dated Octo- 
ber 30, 1916, issued by the United States 
Department of Agriculture, or as determined 
by any device giving equivalent results. 

Sec. 10. Percentage of Moisture. — Percent- 
age of moisture in wheat shall be that, or 
the equivalent of that, ascertained by the 
moisture tester and the method of use there- 
of described in Circular 72, and supplement 
thereto, issued by the United States Depart- 
ment of Agriculture, Bureau of Plant Indus- 
try. 



Sec. 11. Heat-damaged Kernels. — Heat- 
damaged kernels shall be kernels of wheat 
which have been distinctly discolored as a 
result of heating caused by fermentation. 

Sec. 12. Inseparable Foreign Material. — 
Inseparable foreign material shall include 
all matter other than wheat which is not 
separated from the wheat in the proper de- 
termination of dockage. 

Sec. 6. Mixed Wheat. — Mixed wheat shall 
be any mixture of wheat not provided for 
in the classes from I to VI, inclusive, defined 
in Section 5. 



GRADES FOR MIXED WHEAT. 

Sec. 21. Grades for Mixed Wheat. — Mixed 
wheat shall be graded and designated ac- 
cording to the grade requirements of the class 
of wheat which predominates over each other 
class in the mixture. There shall be added 
to, and made a part of, its grade designation 
the word "Mixed'' and the names of the 
classes which compose the mixture, in the 
order of their predominance, together with 
the approximate percentage of each class, 
except that, if the wheat of any class amounts 
to less than ten per centum of the whole 
mixture, its name and percentage, need not 
be stated. 

Sec. 8. Treated Wlieat. — Treated wheat 
shall be wheat which has been scoured, limed, 
washed, or treated in any similar manner. 

GRADES FOR TREATED WHEAT. 

Sec. 23. Grades for Treated Wheat. — Treat- 
ed wheat shall be graded and designated ac- 
cording to the grade requirements of the 
standard applicable to such wheat if it were 
not treated, and there shall be added to, 
and made a part of, its grade designation 
a statement indicating the kind of treat- 
ment. 

Sec. 7. Smutty Wheat. — Smutty wheat 
shall be all wheat which has an unmistakable 
odor of smut, or which contains spores, balls, 
or portions of balls, of smut, in excess of a 
quantity equal to one ball of average size in 
fifty grams of wheat. 



GRADES FOR SMUTTY WHEAT. 

Sec. 22. Grades for Smutty Wheat. — 

Smutty wheat shall be graded and desig- 
nated according to the method described eith- 
er in paragraph (a) or paragraph (b) of this 
section. 

(a) The loss in weight caused by the re- 
moval of smut from the wheat, when free 
from dockage, shall be ascertained by scour- 
ing, washing, or otherwise, and shall be cal- 
culated in terms of percentage based on the 
total weight of the grain free from dockage. 
The percentage so calculated shall be stated 
in terms of whole per centum and half 
per centum. A fraction of a per centum when 
equal to, or greater than, a half, shall ba 
treated as a half, and when less than a 
half shall be disregarded. After the loss in 
weight caused by the removal of the smut 
has been ascertained, the wheat shall be 
graded and designated according to the grade 
requirements of the standard applicable to 
such wheat if it were not smutty, and there 
shall be added to, and made a part of, the 
grade designation the percentage so deter- 
mined and stated together with the words 
' ' smut dockage. ' ' 

(b) Smutty wheat shall be graded and 
designated according to the grade require- 
ments of the standard applicable to such 
wheat if it were not smutty, except that 
when the amount of smut present is so great 
that any one or more of the grade require- 
ments of the grades from No. 1 to No. 5, 
inclusive, cannot accurately be applied, the 
wheat shall be classified as sample grade. 
For all grades there shall be added to and 
made a part of the grade designation the 
word ' ' Smutty. ' '

GRAIN SIEVES. 

For the Determination of Dockage Under the 

Oflacial Grain Standards of the 

United States for Wheat 

Sieves and bottom pan for each set should 

be circular in shape and made of aluminum, 

brass or other suitable material. The metal 

should be .025 to .035 inches in thickness. 



Scalper Sieve: — perfor- 
ations 12-64 inch in 
diameter 



Buckwheat Sieve : — per- 
forations exactly 8-64 
inch on each side 



▼ ▼ ▼ ▼

▼ ▼ ▼ ▼ ▼ 




Fine Seed Sieve: — per- Chess Sieve: — perfor- 

f orations exactly 1-12 ations exactly 4*4-64 

inch in diameter inch x 3^ inch 

(a) Bottom Pan — Inside diameter should be 

13% inches; depth 2% inches; and roll at 

top of pan ^5 inch in diameter. 

NOTE— Sieves should be made to nest very 'freely 
with the bottom pan. The scalper sieve should Jnest very 
freely with each of the other sieves and also with the 
bottom pan. 

The accompanying views of sections of perforated 
metal s<how the arrangement and kind of perforations 
desired and the proportional amount of metal between 
perforations. The perforations should be the exact size 
as griven in the specifications for the sieves and should 
extend completely across the bottom and up to the sides 
of each sieve. The smooth surface of the metal should 
face up.
